AA-PersonalityBench AA-PersonalityBench is a new benchmark that measures the personality of language models across 30 traits rolled into eight indexes (Expressiveness, Organization, Informativeness, Transparency, Warmth, Conviction, Imagination, and Slop) and 21 communication characteristics such as response length, table use, em dashes, and emoji. It evaluates answers to 900 curated questions using pairwise LLM judges for traits and programmatic analysis for style.
